I've been a Diva user for quite a while and just had to replace my cup. Lots has changed since I got my last one - now, in addition to the C-fold, the punch-down fold is also shown, both on the directions booklet and on the outer packaging. The way they describe the fold could be confusing to a first-timer, but I still think it's a step in the right direction. Someone in their marketing department must have been listening to feedback. Cool beans!
Forgive me if this is old news, but I haven't seen it mentioned anywhere yet and I thought it was pretty sweet. :)
